What is the atomic mass of Re 185?
The element rhenium (Re) has two naturally occurring isotopes, 185Re and 187Re, with an average atomic mass of 186.207 amu. Rhenium is 62.60% 187Re, and the atomic mass of 187Re is 186.956 amu. Calculate the mass of 185Re.
What is the average atomic mass of neon?

What is the mass of an atom of silver?
Why gold is called Au?
Gold is element 79 and its symbol is Au. Though the name is Anglo Saxon, gold originated from the Latin Aurum, or shining dawn, and previously from the Greek. They are found naturally and were the first three elements known to man.
Where silver is found in nature?
Silver is sometimes found in nature as a free metal but also appears with other minerals and deposits of ore like copper, gold, nickel, lead and lead-zinc. Silver is heavily mined around the world with the largest deposits being mined in China, Australia, Peru, Poland, Serbia, Bolivia, Mexico and Chile.
Is gold a metal?
In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal and a group 11 element.
Why silver is so important?
It has the highest electrical conductivity of any element and the highest thermal conductivity of any metal. Silver occurs in pure form, as an alloy with other metals or in minerals. Moreover, silver ions and compound can kill bacteria, algae, and fungi; therefore, silver helps purify, sanitize, and filter water.
What is the use for gold?
Pure gold is soft and is usually alloyed with other metals, such as silver, copper, platinum or palladium, to increase its strength. Gold alloys are used to make jewelry, decorative items, dental fillings and coins. The amount of gold in an alloy is measured with a unit called a karat.
How heavy is silver?
A cubic foot of iron would weigh 491 lb. A cubic foot of copper would weigh 559 lb. Silver is even denser than copper, at 655 lb for a cubic foot. Gold is really heavy at 1206 lb for a cubic foot.
Is a silver magnetic?
In fact, only iron, nickel, cobalt, gadolinium, neodymium and samarium are magnetic in our everyday lives. Knowing that silver isn’t magnetic is useful since it can help you spot fake silver. For example, if someone is trying to sell silver jewelry or coins it’s not a bad idea to test them with a magnet.
What are the properties of silver?
Of all the metals, silver is the best conductor of heat and electricity known, in fact it has the highest electrical and thermal conductivity known for any material. It is strong, malleable and ductile, and can endure extreme temperature ranges. Silver is also able to reflect light very well.
What is the use of silver?
It is used for jewellery and silver tableware, where appearance is important. Silver is used to make mirrors, as it is the best reflector of visible light known, although it does tarnish with time. It is also used in dental alloys, solder and brazing alloys, electrical contacts and batteries.
How many protons and neutrons does gold have?
NameGoldAtomic Mass196.967 atomic mass unitsNumber of Protons79Number of Neutrons118Number of Electrons79
Is silver a metal?
The metal is found in the Earth’s crust in the pure, free elemental form (“native silver”), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining. Silver has long been valued as a precious metal.
What is the silver used for?
Silver has also been used to create coins, although today other metals are typically used in its place. Sterling silver, an alloy containing 92.5% silver, is used to make silverware, jewelry and other decorative items. High capacity batteries can be made with silver and zinc and silver and cadmium.
How many protons are in an atom of silver?
Structure of the Silver Atom. The silver atom has 5 electron orbits (energy levels) with a total of 47 electrons. Beginning with the orbit closest to the nucleus and working outward, the number of electrons per orbit should be: 2, 8, 18, 18, 1. Of course, the nucleus contains 47 protons and 61 neutrons.
What is a normal phase of silver?
Density: 10.501 grams per cubic centimeter. Phase at room temperature: Solid. Melting point: 1,763.2 degrees Fahrenheit (961.78 degrees Celsius) Boiling point: 3,924 F (2,162 C)
When gold was discovered?
Gold Discovered in California. Many people in California figured gold was there, but it was James W. Marshall on January 24, 1848, who saw something shiny in Sutter Creek near Coloma, California. He had discovered gold unexpectedly while overseeing construction of a sawmill on the American River.
What are some of the physical properties of silver?
What are the Physical Properties of Silver?ColorWhiteConductivityExcellent electrical and heat conductor. It has the highest electrical and thermal conductivity of any metalSolubilitySolubility (ability to be dissolved)HardnessA relatively soft metal
What is the valence of silver?
Silver is a group 11 transition metal in the 5th period of Periodic table with symbol Ag (Argentum from Latin word). In most case the valency of Ag is 1, as the d sub-shell has stable configuration if they loss 1 electrons from s sub-shell. There fore the most common valency of silver is 1.
Is silver a reactive?
It is not reactive. It does not dissolve in most acids. Nitric acid dissolves it, though, to make silver nitrate. It does react with strong oxidizing agents like potassium dichromate or potassium permanganate.
How many electrons and protons does platinum have?
NamePlatinumAtomic Mass195.078 atomic mass unitsNumber of Protons78Number of Neutrons117Number of Electrons78
